Function assignment of external terminal and control
90 190 Y90 Life alarm
Output when any of the control circuit
capacitor, main circuit capacitor and inrush
current limit circuit or the cooling fan
approaches the end of its service life.
Pr. 255 to Pr. 259 374
91 191 Y91
Alarm output 3
(power-off signal) Output when an error occurs due to the circuit
failure or connection alarm of the inverter.

92 192 Y92
Energy saving
average value
updated timing
Turned on and off alternately every time the
power saving average value is updated when
the power saving monitor is used.
Cannot be set to
Pr. 195 and Pr. 196 (relay
output terminal).
Pr. 52, Pr. 54,
Pr. 158, Pr. 891 to
Pr. 899
267
93 193 Y93
Current average value
monitor signal
Average current value and maintenance timer
value are output as pulses.
Cannot be set to
Pr. 195 and Pr. 196 (relay
output terminal).
Pr. 555 to Pr. 557 378
94 194 ALM2 Alarm output 2
Output when the inverter protective function
is activated to stop the output (major fault).
Continue outputting the signal during inverter
reset and stop outputting after reset is
cancelled.

95 195 Y95
Maintenance timer
signal Output when
Pr. 503
rises to or above the
Pr.
504 setting.
Pr. 503, Pr. 504 377
96 196 REM Remote output
Output to the terminal when a value is set to
the parameter.
Pr. 495 to Pr. 497 241
97 197 ER Minor fault output 2
When
Pr. 875
= "0" (initial value), the signal is
output when the inverter protective function is
activated to stop the output (major fault).
When
Pr. 875 = "1", the signal is output when
the inverter protective function is activated at
occurrence of OHT/THM/PTC error and
deceleration is started.
Output when other protective functions are
activated to stop output. Pr. 875 265
98 198 LF Minor fault output
Output when a minor fault (fan failure or
communication error warning) occurs.
Pr. 121, Pr. 244 320, 373
99 199 ALM Alarm output
Output when the inverter protective function is
activated to stop the output (major fault). The
signal output is stopped when a reset turns on.

*1 Note that when the frequency setting is varied using an analog signal or of the operation panel (FR-DU07), the output of the SU (up to
frequency) signal may alternate on and off depending on that varying speed and the timing of the varying speed due to acceleration/deceleration
time setting. (The output will not alternate on and off when the acceleration/deceleration time setting is "0s".)
*2 When a power supply reset is performed, the alarm output 2 signal (ALM2) turns off as soon as the power supply switches off.
*3 Up to frequency SU, frequency detection FU, FU2, FU3 under encoder feed back control or vector control (option FR-A7AP is mounted) signals
are as below.
SU, FU: Output when the actual speed (frequency) by the encoder feedback signal exceeds detected specification frequency.
FU2, FU3: Output when the inverter output frequency exceeds detected specification frequency.
*4 This function is valid when the FR-A7AP (option) is mounted.
REMARKS
⋅
The same function may be set to more than one terminal.
⋅
When the function is executed, the terminal conducts at the setting of any of "0" to "99", and does not conduct at the setting of
any of "100" to "199".
⋅
The signal will not function if a value other than the above is set to any of Pr. 190 to Pr. 196 .
⋅
When Pr. 76 Alarm code output selection = "1", the output signals of the terminals SU, IPF, OL and FU are switched as set in Pr.
76 . (When an inverter alarm occurs, the signal output is switched to the alarm output.)
⋅
The output assignment of the terminal RUN and alarm output relay are as set above regardless of Pr. 76 .
CAUTION
⋅
When terminal assignment is changed using Pr. 190 to Pr. 196 (output terminal function selection) , the other functions may be
affected. Please make setting after confirming the function of each terminal.
⋅
Do not assign signals which repeat frequent ON/OFF to A1, B1, C1, A2, B2, C2. Otherwise, the life of the relay contact
decreases.
